How to Take It
Best taken in the evening
Contains Tryptophan, so it belongs in the evening. Take it with food — the choline in it is what makes this kind of product feel nauseating on an empty stomach.
With food
Tryptophan does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Keep it away from protein-heavy meals
Space it a couple of hours from Iron, Calcium and SAMe
On the label
Mix 2 scoops into your morning coffee, milk of choice or smoothie
The label says morning, but the Tryptophan in it makes evening the safer call.
Do not combine with St. John's Wort
Each of these raises serotonin activity on top of St. John's Wort, and together they can trigger serotonin syndrome — agitation, rapid heartbeat, raised blood pressure. Not without medical supervision.
General guidance based on the ingredients, not a substitute for the label or your doctor.
